2. Functional Description
The ProSLIC
that provides all the SLIC, codec, DTMF detection, and
signal generation functions needed for a complete
analog telephone interface. The ProSLIC performs all
battery, overvoltage, ringing, supervision, codec, hybrid,
and test (BORSCHT) functions. Unlike most monolithic
SLICs, the Si3210 does not require externally-supplied
high-voltage battery supplies. Instead, it generates all
necessary battery voltages from a positive dc supply
using its own dc-dc converter controller. Two fully-
programmable tone generators can produce DTMF
tones, phase continuous FSK (caller ID) signaling, and
call progress tones. DTMF decoding and pulse metering
signal generation are also integrated. The Si3201
linefeed interface IC performs all high-voltage functions.
As an option, the Si3201 can also be replaced with low-
cost discrete components as shown in the typical
application circuits in Figures 12, 13, and 14.
The ProSLIC is ideal for short loop applications, such as
terminal adapters, cable telephony, PBX/key systems,
wireless local loop (WLL), and voice over IP solutions.
The linefeed provides programmable on-hook voltage,
programmable off-hook loop current, reverse battery
operation, loop or ground start operation, and on-hook
transmission ringing voltage. Loop current and voltage
are continuously monitored using an integrated A/D
converter. Balanced 5 REN ringing with or without a
programmable dc offset is integrated. The available
offset, frequency, waveshape, and cadence options are
designed to ring the widest variety of terminal devices
and to reduce external controller requirements.
A complete audio transmit and receive path is
integrated, including DTMF decoding, ac impedance,
and hybrid gain. These features are software-
programmable, allowing for a single hardware design to
meet international requirements. Digital voice data
transfer occurs over a standard PCM bus. Control data
is transferred using a standard SPI. The device is
available in a 38-pin QFN or TSSOP package.
2.1. Linefeed Interface
The ProSLIC’s linefeed interface offers a rich set of
features and programmable flexibility to meet the
broadest applications requirements. The dc linefeed
characteristics
current, voltage, and power measurements are acquired
in real time and provided in software registers.
